Application January 18 This invention relates toan improved slide loop for holding straps on apparel or other uses at which adjustability is desirable.

' The invention also resides in an improved 5 method of making such slide new article. i d

The object of the invention isto provide a' loops to provide the buckle or slide which holds a strap against any side movement for punching whatsoever which in turn avoids any canting of thearticle onthestrap. Furthermore, the cross-arm or bar of the loop is materially strengthened by. a novel construction of its edge which is the portion that providesfthe improved gripping and spreading portion of .the

It has been customary in loops or punching the :teeth back. I'I'his form oftooth presents only one corrugated engaging the strap.

The improvement in this case tion of teeth inv thefform of a corrugated flange which corrugations extend from front to rear .to form teeth on both the front and edgesof the flange, that is, on the front and rear of the crossbar.
